The mechanical properties, creep rupture strength, creep damage and failure characteristics of dissimilar metal welded joint (DMWJ) between martensitic (SA213T91) and bainitic heat-resistant steel (12Cr2MoWVTiB) have been investigated by means of pulsed argon arc welding, high temperature accelerated simulation, mechanical, creep rupture test, scanning electronic microscope (SEM). The results show...
Effect of W on creep strength of martensitic steels was investigated paying special attention to microstructural degradation during creep. Though tempered martensitic lath structure is stable at the elevated temperatures without stress, its recovery takes place substantially during creep. After the recovery, lath width and dislocation density in lath interior reached the stationary values determined...
